" strainer.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description beingsupplemented by the aecompanying drawing.

Figure l is a vertical sectional view of a strainer constructed in accordance with my invention.

Figure 2 is a horizontal sectional View on line 2 2 of Fig. l. Y

Figure 3 is a vertical sectional view of the removable sediment collecting cup.

Figure 4 is an elevation partly in section, showing the shield which prevents appreciable upward surging of sediment. from the collecting cup.

ln the drawing above briefly described, the numeral l designates a vertically disposed tubular member having an upper straining portion 2, preferably formed of woven wire, and a lower portion 3 in the form of a continuous imperforate wall which is soldered or otherwise secured at l to the straining portion 2. The upper end of the member l is soldered at 5 or secured in some other suitable way to a collar 6, and I said member is adapted to be downwardly inserted through the filling neck of a tank, the collar 6 being formed with an outstanding flange 7 to rest on said neck. This flange may be cut to any desired size and its upper side may be provided with a number of circular guide lines (not shown) to assist in cutting said flange to the necessary size.

vertically spaced baffle plates 8 have been shown within the wall 3, extending inward- Aly from opposite sides of said wall and declining toward their inner ends. Below these plates, I have shown the wall 3 formed with screw-threads 9 by means of which a sediment collecting cup l0 is detachably 4connecrLed with said wall. VVithinthis cup and' spaced from its side wall and bottom, is

a si'iieldwhich Iis preferably in the form of conicalplate ll.v Secured to and extending downwardly from the center of the plate l1,

is an attachingshank l2 which is preferably v v tulmlar,i Isaid jshankv `beingl removably rec'eived4 -in a'short upright tube 18 which is secured to the bottom of the cup 10.

Fheny using'the device, vthe gasoline or otherA liquidlis discharged into-the upper end ofVV the member 1,/and" the portion A2 thereof iilters'and strains the liquid, so that- 'any watertor other foreign matter is trappedy in the ldevice 'and'l'willinally settle between the baffle plates 8 and reach the shield 1l.

The shape of this shield directs the settling material toward rthe wall of the cup so that it will descend to the bottom of the latter, and thereafter, saidshield has a tendency to prevent upward surging of any sediment. The plates 8 prevent violent agitation of the liquid within the cup l0, when other liquid is being discharged into the upper end of the member l and consequently there is no danger of stirring the sediment in the cupv and again mixing it with the liquid. From time to time, the entire device may be re-y moved from the tank, the cup 10 detached, the shield 11 removed, and the cup thoroughly cleaned. When reassembled, the device is inreadiness for further efficient use.

is excellent results may be obtained from the details disclosed, they may well be followed, but within the scope of the invention as claimed, numerous minor changes may be made. y

I claim:

l. In a liquid straining device, a vertically said shield being imperforate and of slightly less diameter than the cup, and means secured to the bottom of the cup to detachably support the shield in its central position above seid bottom to prevent epprecisible upward surgingl of the sediment.

2. in e liquid straining device, a vertically disposed tubular member open at its upper `and lower ends and comprising an upper iomminous straining portion and an imperiorete continuous wall at the lower end or seid straining portion; an imperforate sedi- .nient collecting cup detechably connected with the lower end of said wall, baille plates within seid wall to prevent violent agitation oit' sediment in the'cup when discharging. liquid inio the upper endof the device,

u short tube secured centrally to and rising from the bottom of said cup, and a shield having a shank removably receivedin said short tube, said shield being` spaced from the bottom and side well of the cup and being` adapted to prevent appreciable upverd surging or' sediment in4 said cup.

3. ln a liquid straining device7 zt vertically disposed tubular straining member open at both ends, a sediment collecting cup dewardly extending` central shank, and a short ktube secured to the cup bottom and removably receiving said shank.

4. In eliquid straining device, n vertically disposed tubulaistraining member open et bothvends, a sediment collecting cup detacoebly connected with the lower end ofV said tubular member, e shield in said cup spaced from the bottom and side wall-thereof to prevent appreciable upward surging of the sediment, said shield being in the form of a conicalv plate having a downwardly e);- tendingshank, and a short tube secured to the cup bottom and removably receiving` said shank. i

n testimony whereof I have hereunto ai"- xed my signature. Y
